It’s reported that scientists in London have found the best diet for both humans and the planet.

If the world followed the so-called “planetary health” diet, each year more than ll million early deaths could be avoided according to the scientists. For the health of the planet, they say the same diet will reduce (减少) greenhouse gases and save more land, water and animals. This new food plan is the result of a three-year project organized by The Lancet health journal.

Tim Lang, a professor at Britain’s University of London. He said, “The food we eat and how we produce it decide the health of people and the planet.” Lang added, The world’s population is expected to grow to 10 billion people by 2050. If we want to feed everyone, we all need to change what we eat and the way we eat by improving food production and reducing food waste”. So, what do you eat on the “planetary health” diet?

The scientists who created the “planetary health” diet say it is largely plant-based but still has a little milk, fish and meat. The diet calls for cutting down red meat and sugar by 50 percent and increasing nuts, fruits, and vegetable.

Walter Willet of Harvard University in the United States also talked about the “planetary health” diet. He said, “More than 800 million people around the world do not get enough food while many more people have very unhealthy diets.”

The scientists think it difficult to reach their aim. But for them, doing nothing is also not a choice Willet said, “If we can’t make the best diet, it’s better to try and get as close as we can.”

1.What decides the health of people and the planet according to Tim Lang?

A.The taste of the food.

B.The number of population.

C.The climate and our living conditions.

D.The food we eat and the way we produce it.

2.What does the “planetary health” diet mainly contain?

A.Milk. B.Meat.

C.Sugar. D.Plants.

3.What do scientists say about the “planetary health” diet?

A.It is very easy to produce it.

B.It is better to try their best to make it.

C.It is better to do nothing than fail.

D.It is impossible to make it.

4.What is the best title for the text?

A.Humans Health Is Very Important.

C.A New Kind of diet may Save the Plane.

D.Different People have Different Eating Habits.

Scientists at the California Institute of Technology (Caltech) have reported evidence that Mars was warmer and wetter long ago than it is today.  The Caltech scientists say they have directly established the temperature of Mars four billion years ago. At least, they established the surface temperature on part of the planet at that time. The researchers say it is the first such evidence to be discovered and presented.

The Caltech scientists say carbonate（碳酸盐）minerals formed on Mars at about eighteen degrees Celsius. They reached the finding after studying a meteorite（陨石）that had its beginnings near the Martian surface.

Today, the average temperature on Mars is sixty-three degrees below zero Celsius.

The finding was reported on the website of the National Academy of Sciences. Caltech Assistant Professor Woody Fischer helped to prepare the report. He says eighteen degrees Celsius is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the planet had liquid water. Spacecraft orbiting Mars have shown what appear to be rivers, lakebeds and mineral deposits. These pictures suggest that, at one time, water did flow there. Mars Rover vehicles and other spacecraft have proved the information.

The meteorite the scientists examined is one of the oldest known rocks in the world. It is called the Allan Hills meteorite. Its name came from the place in Antarctica where it was found in 1984. The meteorite is believed to have blown loose from the Mars' surface when another space rock struck its "home."

1.The underlined word “establish” in Paragraph 1 probably means “___________”.

A. to set up　

B. to make people accept a belief

C. to discover or prove

D. to start having a relationship with others

2.How did the scientists reach the finding?

A. By studying Allan Hills meteorite.

B. By using spacecraft orbiting Mars.

C. By studying minerals gathered on Mars.

D. By studying a meteorite on the Martian surface.

3.According to the fourth paragraph, what have spacecraft orbiting Mars done?

A. Measuring the temperature of Mars.

B. Taking photos of the surface of Mars.

C. Finding that there is water flowing on Mars.

D. Proving where human beings will probably land on Mars.

4.Where can we most probably read this passage?

A. In a biography of scientists.    B. In a geography magazine.

C. In an environment report.    D. In a science report.

Scientists may have found a way to reduce shortage of type O blood. Type O is the kind of blood that hospitals most often need. What the researchers are testing is an easier way to make type O blood out of other kinds of blood.

There are four main kinds of blood. Most people born with one of these four: Type A,Type B, Type AB or Type O. Type O can be safely given to anyone. So it is commonly used when a person is injured or sick and has to have blood.

The differences among blood types are linked to whether or not red blood cells contain certain kinds of sugar molecules(分子). These molecules are found on the surface of the cells.They are known as antigens (抗原). These antigens are found with type A, B and AB blood but not with type O.

More than twenty-five years ago, scientists found that the antigens could be removed to create what they called universal-type cells. They could be removed with chemicals called enzymes(酶). But large amounts of enzymes were required to make the change.

Doctor Henrik Clausen of the University of Copenhagen in Denmark led the study. The next step, he says, is to complete safety tests. The team is working with the American company ZymeQuest to test the new method. If it meets safety requirements(*k)and is not too costly,it could become a widely used life-saving tool to increase the supply of universal blood.

1.How do scientists deal with the problem of lacking type O blood?

A.Hope more people to donate type O blood.

B.Make the most of the present type O blood.

C.Develop new ways of using type O blood.

D.Make type O blood out of other kinds of blood.

2.What make people have different kinds of blood?

A.Sugar molecules in red blood cells.

B.People's different living conditions.

C.Peoples various immune systems.

D.The variety of peoples cells and genes.

3.What can we infer from the text?

A.Type O blood can be safely given to anyone

B.Antigens could easily be removed to create universal blood.

C.A Danish company wanted to involve itself in studying blood.

D.The new method is not safe enough to be put into use in hospitals now.

4.What is the best title for the text?

A.Four different kinds of blood

B.A new way to make type O blood

C.The latest research on blood type

D.Find the proper type of blood

Scientists say they now have proof to support the old-fashioned advice that it's best to sleep on a problem. They say sleep strengthens the memory and helps the brain organize the masses of information we receive each day.

Lead researcher Bob Stickgold at the Harvard Medical School said, "Sleep helps us draw rules from our experiences. It's like knowing the difference between dogs and cats even if it's hard to explain."

The US research team studied how well students remembered connections between words and symbols (象征) , reports New Scientist. They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept. They found that people were better able to remember lists of related words after a night's sleep than after the same time spent awake during the day. They also found it easier to remember themes (主题) that the words had in common. But they forgot around one in four more themes if they had been awake. Prof. John Groeger, of Surrey University's Sleep Research Centre, said, "People have been trying for years to find out what the purpose of sleep is, as we know that only certain parts of it have a restorative (有助恢复的) value. " "We form and store huge numbers of experiences in the head every day, and sleep seems to be the way the brain deals with it all."

1.The phrase" to sleep on a problem" in Paragraph 1 most likely means to______.

A. pay full attention to a problem                         B. wait until later for a decision

C. sleep to forget a problem                                  D. have difficulty sleeping

2.In the study by the US research team, students were asked to______.

A. put together words of similar meanings

B. remember words and their meanings

C. show their knowledge of words

D. make up lists of related words

3.Which of the following may be easier to remember?

A. Themes learned right before the test

B. Rules from personal experience

C. Words learnt before a good sleep

D. Ideas stored together in the brain

4.What may be the importance of the research?

A. It shows sleep may help us manage information

B. It helps find out the common themes of word

C. It tells us that more sleep can improve health

D. It proves the value of old-fashioned advice
